During subduction, as one plate dives into the depths beneath another, we think part of the rock melts and eventually finds its way back to the surface in the form of volcanoes. In fact, most of the world"s volcanoes and earthquakes occur at plate boundaries. This is what you"d expect....
However, the largest oceanic normal fault earthquakes occur near subduction zones where the lithosphere is bending. Laboratory studies indicate that bending lithosphere likely has a higher yield stress than lithosphere in pure extension, which may allow for larger oceanic normal fault earthquakes. ...
one that others have tried and failed to perfect, but now it seems to be living the promise.Folks at UCLA Berkeley 0ffer a free bit of softwarefor your phone. It’s an accelerometer that “records earthquakes as they happen”. The only thing that would be better would be an app that r...
The crust along a divergent boundary is some of the newest crust on earth. Explain why. Plate Tectonics: The theory of plate tectonics deals with the dynamics of the earth's outermost layer (also known as the lithosphere). The theory gives a satisfying explanation for...
Subduction can be a violent process. It's no coincidence that mostundersea earthquakesand volcanoes are concentrated near faults in the seabed. High-resolution seabed maps can help scientists predict catastrophic geologic events before they happen, which may reduce the impact on nearby populations. ...
